Robot-Assisted Laparoscopic Removal of a Large Primary Retroperitoneal Mature Cystic Teratoma in an Adult

Abstract

Mature teratomas are unique and generally benign neoplasms. They are derived from embryonic tissues and typically located within the gonadal region. Primary retroperitoneal teratomas are uncommon in adults and often challenging to treat, given their location and size. Here, we offer a rare case of a large primary retroperitoneal mature cystic teratoma, detected on abdominal ultrasound during the work-up of abdominal bloating and nausea and treated with robot-assisted laparoscopic excision in a 58-year-old male. In this report, we sought to describe the evaluation, treatment, and follow-up of this condition, as well as review the associated literature.

“… 29 A robot-assisted laparoscopic approach is even more scarcely reported in the literature. 30 While a robot-assisted laparoscopic approach has been successfully reported in previous literature, our facility did not have a robotic surgical system in order to consider this option. The laparoscopic approach does have drawbacks, including the need for advanced surgical training and the lack of direct touch to discern tumor boundaries.…”
